Title: Device for decoding compression data of moving image
Inventor: MORI NATSUKI
IPC: H04N19/51
Filed: 1996-06-28
Abstract: PROBLEM TO BE SOLVED: To reduce the disturbance of a decoded display picture as small as possible when a decoding error is generated in a variable length code. SOLUTION: At the time of decoding a variable length code from the code bit string of moving image compression data, a variable code decoding part refers to a variable length code table, and when a corresponding variable length code is not entered, generates a decoding error detection signal. When an Nth picture in decoding is an intra-frame encoded picture data (I picture) or inter- frame forward direction predictive encoded picture data (P picture), a movement compensating part substitutes unit data corresponding to the (N-1) th I or P picture stored in a memory area for a unit data area (slice line data) including an error occurance block to obtain a decoded display picture.  When the picture in decoding is a bidirectional predictive encoded picture data (B picture), unit data corresponding to the (N-1) th picture movement-compensated and stored in a display memory are substituted for the unit data including the error occurance block, so that the display of the slice line data including the error occurance block and having the possibility of incorrect data can be suppressed.
